Check Digit Verification of cas no
The CAS Registry Mumber 135-76-2 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 1,3 and 5 respectively; the second part has 2 digits, 7 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 135-76:
(5*1)+(4*3)+(3*5)+(2*7)+(1*6)=52
52 % 10 = 2
So 135-76-2 is a valid CAS Registry Number.
